The Finsrud Wheel is a moving sculpture built by Norwegian artist Reidar Finsrud. It appears to use a combination of gravity, magnets, and pendulum effects, which modern physics would say is impossible, to generate 'nearly continuous motion since 1996' when it was assembled. It is presently housed in a vault in a Norwegian gallery featuring Finsrud's works.

: 14-days in a row is the longest it has run without stopping. -- Rita Børtveit, on behalf of Reidar Finsrud (April 2, 2008)

There are many pictures, videos and discussion boards available on the web and from journalistic sources. This page is an attempt to bring together a critical understanding of the machine, extracting from various sources the best positive and negative writings available.

We 'don't know of any replications' of the device, succussful or unsuccessful, even though what seem to be a full set of drawings are provided.

There would appear to be 'no practical applications' of this device in its present mode. Further refinements and optimization would be required for it to become practical as an energy generator.

English Translation (by Jan Klyve via Sepp Hasslberger) : NOTE: the machine is much more complicated than it appears at first sight. The upper part of the system is, among other things, absolutely decisive for the machine's function. These "blade springs" transfer (steal) a little of the ball's kinetic (motion-) energy and this energy is used to lower the track ca. 200 micrometers, just a bit ahead of the ball. The energy is transferred via the frequency of the blade springs. The entire machine "floats" and is dependent on the central pendulum, the three large pendula, the speed of the ball, the frequency of the blade springs and everything else being in harmony - or "tuned", "calibrated" in relation to each other. You can read about the fundamental (basic) energy here. http://www.keelynet.com/energy/finsrud.htm

Finsrud's Perpetuum Mobile - Over 40 min of continuous work is shown of a perpetuum mobile constructed by Reidar Finsrud of Norway. This is the first public display of a working perpetuum mobile in modern history.. (Google Video Sep 6, 2006)

Perpetual Motion - analyzing the Finsrud GMD (IPMM 6) - Analysis of Finsrud's machine by Anand Aadhar. The conclusion is:."If we repel or expand from a diallel - towards the center - array of magnets and counter that force with the contraction or attraction of gravity driven magnets, then we can make a motor run given a cyclic setup containing a vibrating feedback loop." Discussed is a short history of the machine and the component parts. Theoretical explanations are offered. 1 minute example of IPMM replication research. (YouTube video 28 januari 2009)

Finsrud Himself has seen this video, said an answering email from his gallery upon offering this video with some technical questions. He answered no scientfic questions like e.g. as to how the magnet array would look like, but it was said that Mr. Finsrud "is impressed with your work, research and seriousness regarding this project."

Drawings

Drawings (~16 in all click on the image displayed, then click on the next button to view all in that set two sets in all)

Advantages

Runs 24/7/375

Disadvantages

Complex

High cost per energy output.

Needs stationary setting could be disrupted by earth tremors

Probably difficult to get running and to tune.

Applications

Does not appear to have any practical application in its present mode, but is just interesting. Further refinements and optimization would be required for it to become practical as an energy generator.

Finsrud perpetual motion machine - at least two people said they would try to replicate the design, but as of March 31, 2008, there are not reports of anyone actually doing this. (commenced April 02, 2005)
